Inventor: HAWARD ROBERT NOBBS
IPC: C08F10/00
Filed: 1969-01-23
Abstract: 1299863 Polymerizing olefins SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 16 Dec 1969 [23 Jan 1969] 61213/69 Heading C3P Olefin polymers are prepared by a process comprising contacting the monomer(s) with a catalyst prepared by the reduction of a transition metal compound in its normal maximum valency state with an organo-magnesium compound, and activation of the reduction product with an organo-aluminium compound, in which at least part of the polymerization is carried out in the gas phase in the substantial absence of a reaction solvent. In preferred embodiments the polymerization reaction is a two-stage procedure in which the gas phase polymerization is preceeded by a pre-polymerization step in which the catalyst is contacted with the olefin monomer in the presence of a reaction solvent, and the reduction of the transition metal compound by the organo-magnesium compound is carried out below 0‹ C., the reaction product being activated with a trihydrocarbyl-aluminium compound. In the example TiCl 3 , prepared by the reaction of TiCl 4  and the reaction product of Mg and n-dodecyl bromide in an aliphatic hydrocarbon solvent, is added to (i-C 4 H 9 ) 3 Al in hexane and an ethylene/hydrogen mixture is fed in for the pre-polymerization step. The hexane is removed and fluid bed polymerization takes place as the ethylene/hydrogen feed continues.

Title: Improvements in pipeline systems and methods of installing them
IPC: F16L59/07
Filed: 1969-12-24
Abstract: 1291097 Insulating pipes and cables KERNFORSCHUNGSANLAGE JULICH GmbH 24 Dec 1969 [27 Dec 1968] 62830/69 Heading F2P [Also in Division H2] A pipeline system for insulating pipes or cables 1 in a member 21 includes a casing 2 and insulating elements 3, each element 3 having a supporting tube 5, two spacers 6, insulation 10 and rollers 4 on the spacers 6. As shown braces 11 may connect the spacers 6 and tube 5 and the rollers 4 may be mounted on rings 8 which are parts of the spacers 6. The spacers 6 must be made from a material of low thermal conductivity, e.g. stainless steel and may have apertures 7 to further reduce the effective conductivity of the element 3. These apertures 7, apertures 12 in the tubes 12 and the polyester foil of insulation 10 facilitate the evacuation of air from the annular space between the casing 2 and the member 21. To install the system the casing 2 is first laid with access chambers at convenient intervals, the member 21 passed therethrough and then the elements 3 rolled into place from the chambers. This last move is possible because the conical shape of spacers 6 permits the elements 3 to be stacked within the casing to form a continuous insulation. The elements 3 can be made up on site by the use of semi-cylindrical parts and a roll of the insulating polyester foil, and the elements assembled round the end of a member 21 projecting from a length of installed casing 2.

Title: Robot Arm Control
IPC: B25J9/00
Filed: 1978-07-03
Abstract: An automatic machine comprises an articulated arm 12, 13 carrying at its free end a fine displacement mechanism driven by solenoids or electrical linear actuators, the position of which in their range of available movement determines the sign and value of control signals fed to motors controlling the positions of the parts of the articulated arm. Signals for controlling the solenoids or electrical linear actuators are recorded in an initial "teaching" operation of the machine, in which the arm is displaced over a required path, as frequency modulation of a reference signal generated, due to the doppler effect, as the articulated arm is displaced, by transducers linked directly to the free end of the arm by trace wires so that displacements are directly sensed rather than being indirectly sensed from measurements of the relative angles of the parts of the articulated arm. <IMAGE>
